This invention relates to a ventilating system for buildings and aims toprovide a novel system for ventilating and: heating breeders to insurethe health of the chicks housed in the brooders.

An important object of the invention is to provide means whereby freshair may be taken into a building and foul air simultaneously exhaustedtherefrom, at intervals.

A still further object of the invention is .to provide a structure whichwhen used in connection with breeders, will insure against the chicksbeing subjected to a draft of air to impair the health of the chicks.

With the foregoing and other objects, in

view which will appear as the description proceeds, the inventionresides in the combination and arrangement of parts and in the detailsof construction hereinafter described and claimed, it being understoodthat changes in the precise embodiment of the invention herein disclosedmay be made with in the scope of what is claimed, without departing fromthe spirit of the invention.

Referring to the drawings:

Figure l is a vertical sectional view through a brooder constructed inaccordance with the invention.

Figure 2 is a sectional view taken on line i U 22 of r igure 1.

Figure 3 is a sectional view taken on line 3-3 of Figure 2.

Figure t is a vertical sectional view through a modified form ofbrooder.

Figure 5 is a sectional view taken on line 5 of Figure 4. i r In thepresent showing I have illustrated the system as employed in connectionwith a brooder, the reference character 5 designating the brooder whichis. preferably circular in formation, the same being provided with theusual roof 6 having a central opening 7 Supported within the brooder, ata point adjacent to the body thereof, is a circular pipe 8, the pipebeing secured by means of the members 9. This pipe 8 is formed with aplurality of spaced openings 10 so that air may enter the pipe 8, fromwhere it may pass into the vertical pipes 11 that communi- 1928. SerialNo. 274,143.

cate with the pipe 8, as clearly shown by Figure l of the drawings.

As shown, these pipes 11 are secured to the wall of the brooder andextend along the roof section 6, from where they extend upwardly throughthe opening 7 as at 12, the discharge ends of the pipes 11 beingfiushwith the edge of the opening 7 The reference character 13 designates thehover which is frusto-conical in formation, and is supported by means ofthe pipe 14 which is connected with the hover and which extends to apoint so that the discharge end thereof communicates with the atmospherethrough the opening 7.

Openings 15 are formed in the hover, which openings are covered by thecircular member 16 which is spaced from the hover defining a circularpassageway to allow air passing through the openings 15 to pass upwardly{and into the passageways 17 formed by the members 18 that arepositioned over the hover is spacedrelation therewith. Communicatingwith the members 17 is a circular member 19 defining a passageway at theupper ends of the members 18, the last mentioned passageway being incommunication with the atmosphere, through the pipe 14, with the resultthat foul air directed under the hover may escape. V Y

Fresh air is taken into the hover through the pipe 20 that has one endcommunicating with the atmosphere, the opposite end thereof extendingupwardly through the bottom of thehover where it connects with the airchamber 21 disposed directly under the hover and adjacent to the heaterwhich is indicated at 22, so that air in the chamber 21 may be heated.Extending through the hover and connected with the heating chamber 21 isa pipe'23, the upper end of-th'e pipe being providedwith a cap 24 todirect heat downwardly.

The heater 22 may be of any desired type to efficiently heat theinterior of the brooder. A. pipe 25 extends through the opening 7 andcommunicates with the burner 22 to carry oif thecobnoxious gases fromthe burner.

Located in each'of the pipes 11 and 23, and disposed adjacent to thedischarge end thereof, is a-swinging valve 26 which is supplied with anarm 27 to which the operating chains 28 are connected, the chains beingalso connected with the rod 29 that carries a thermostat wafer 30 at itslower end, the wafer being secured to the casing of the heater 22. Theaction of the heat on the thermostat will cause the members 26 to beoperated to open the pipes and allow air to pass therethrough. Theopening 7 is covered by the cap 31 which is disposed in spaced relationwith the roof of the hover to permit air to pass thereunder, but excludeforeign matter therefrom.

In the form of the invention as shown by Sheet 2 of the drawings, thebrooder is indicated by the reference character 5 and is supplied with acircular pipe 8 supported therein, the pipe having a pluralityof'openings to permit air from the interior of the brooder to enter thepipe '8. Pipes 11 communicate with the pipe 8 and extend upwardly havingtheir upper ends extended laterally through the wall of the brooder tocommunicate with the atmosphere and allow air to pass therefrom.

In this form of the invention the hover which is indicated at 13 issupplied with openings over which the members 1% are positioned, whichmembers define passageways for the air passing through the openings inthe hover, there being supplied a pipe 15 communicating with thepassageways to carry off the foul air that otherwise collects under thehover.

The fresh air inlet pipe is indicated by the reference character 16 andextends through the wall of the hover, the discharge endthereof beingsupplied with a valve 17. Valves 17 are also provided in the pipes 11,and as shown these valves are connected with chains 18, which extenddownwardly and connect with the rod 19 that supports the wafer 20, towhich the wafer 20' is connected, the wafer being supported on thecasing of the heater 21. These valves are operated by the action of thethermostat wafer 20 which causes a movement of the rod and chain to movethe valves and allow air to enter through the pipe 16, and allow air toexhaust through the pipes 11.

Supported under the hover 13 is a heater 21 that has a pipe. 22connected therewith and which extends through the top of the hover topermit the products of combustion to pass outwardly therethorugh.
